HYBRID GEOMETRIC CALIBRATION METHOD FOR MULTI-PLATFORM SPACEBORNE SAR IMAGE WITH SPARSE GCPS
SAR image geometric calibration R-D model multi-platform TerraSAR-X TanDEM-X Gaofen-3
2018/5/15
Geometric calibration is able to provide high-accuracy geometric coordinates of spaceborne SAR image through accurate geometric parameters in the Range-Doppler model by ground control points (GCPs). H...

2016/7/4
As the linear array sensor such as multispectral and hyperspectral sensor has great potential in disaster monitoring and geological survey, the quality of the image geometric rectification should be g...
Vectorization of raster data is very important in GIS. Adjacent vertices of vector graphics usually pass though the same vertical or horizontal straight lines after vectorization. This paper proposes ...

A fully automated reconstruction of the trajectory of image sequences using point correspondences is turning into a routine practice. However, there are cases in which point features are hardly detect...
IMAGE ORIENTATION AND OBJECT RECONSTRUCTION VIA POINTS ON COUNTOURS
Surface reconstruction Orientation Mathematical models
2015/1/6
The main task in photogrammetry is the reconstruction of three-dimensional objects - size, shape, position or geometric distance - from analog or digital images. In a first step the camera position an...
